loop inside loop

what theme are you using?

are you planning to build a custom page template?

what exactly do you want to display on the page?

my own theme

start by creating a page template https://codex.www.ads-software.com/Page_Templates, possibly based on page.php of your theme.

https://codex.www.ads-software.com/Class_Reference/WP_Query

then replace the normal loop with this general structure to get all top level pages and then loop through their direct children:

<?php
$top_level_args = array(
  'post_type' => 'page',
  'post_parent' => 0,
  'posts_per_page' => -1
);
$top_level = new WP_Query( $top_level_args );
if( $top_level->have_posts() ) :

	while( $top_level->have_posts() ) :
	$top_level->the_post();

	the_title(); //top level parent page title - add your own HTML for formatting//

	//start inner loop//

	$parent_page_title = $post->post_title;
	$child_level_args = array(
	  'post_type' => 'page',
	  'post_parent' => $post->ID,
	  'posts_per_page' => -1
	);
	$child_level = new WP_Query( $child_level_args );
	if( $child_level->have_posts() ) :

		while( $child_level->have_posts() ) :
		$child_level->the_post();

		the_title(); //child level page title - add your own HTML for formatting//
		the_content(); //child level page content - add your own HTML for formatting//

		endwhile;

		else: echo 'no child page(s) for \'' . $parent_page_title . '\'';
	endif; wp_reset_postdata();

//end of inner loop//

endwhile;

else: echo 'no top level pages';

endif; wp_reset_postdata();

?>

if you also need child pages from lower levels, you need to adapt the code, for example by using 'child_of' instead of

‘parent’

in the inner loop.

function shortcode_parent(){
$args = array(‘post_type’ => ‘vh_accommodation’, ‘orderby’ => ‘title’, ‘order’ => ‘ASC’, ‘post_parent’ => 0, ‘posts_per_page’=>’-1′);
$the_query1 = new WP_Query($args);
echo ‘<h2 style=”background: none repeat scroll 0 0 #dba63f; color: #fff; font-family: Open Sans; font-size: 18px; margin-bottom: 15px; margin-top: 0 !important; padding: 10px; border-bottom: 2px solid #c18c25;”>’;
echo “Rooms Available”;
echo ‘</h2>’;

if($the_query1->have_posts()){
while ($the_query1->have_posts()) {
$the_query1->the_post();
global $thisPost;

$parent_page_title = $post->post_title;
//$thisPost->post_parent;
//echo $thisPost;

$inner_args = array(‘post_type’ => ‘vh_accommodation’, ‘post_parent’ => $post->ID, ‘posts_per_page’ => 5,’orderby’ => ‘title’, ‘order’ => ‘ASC’,);
$inner_query = new WP_Query($inner_args);

if($inner_query->have_posts()){
while ($inner_query->have_posts()) {
$inner_query->the_post();
//echo the_title();
?>

i wrote this codeing but i am running all parent pages all sub pages will be displaying

for any shortcode, you need to 'return' the results instead of 'echo'ing them; https://codex.www.ads-software.com/Shortcode_API

but i am running all parent pages all sub pages will be displaying

what is wrong with the output? what exactly do you want to show?

hi i created
Home Page
subpage1
subpage2
subpage3
Main Page
MainSubpage1
MainSubpage2
MainSubpage3
i need display the content of subpages in Home page/Main Page but i am writing the loop both the pages displaying same content
